5 tips for success
- Grow sweetcorn in blocks, not rows. For cobs to form, the female flowers need to be pollinated by the male flowers. Growing them in blocks allows the wind to more effectively pollinate the plants. That won’t happen if they are planted in a row.
- Make sure plants grow in full sun and in deeply prepared, fertile soil, with a layer of compost as mulch.
- Sow where the plants are to grow – if roots are disturbed by transplanting it delays the growth.
- Space plants 30-35cm apart and with a space of 50-60cm between rows. Spacing too close can also result in poor pollination.
- Cobs must be harvested within 2-3 days of being harvest-ready, when the tassels/silks of the female flowers have completely withered and turned brown. Leaving cobs on for too long results in chewy, inedible cobs.
